Matthew Murdock (aka Daredevil) was born and raised in Hell's Kitchen, in Manhattan, New York City.
One day he sees a blind man crossing the road, and a truck going right at the man.
He quickly pushes the man out of the way, and the truck swerves out of control.
The truck is full of toxic waste, and when it crashes, the toxic waste splashes in his eyes. From that moment on, he was blind.
As a result of the toxins within the truck, his four remaining senses have been greatly intensified. Years later,
his father is killed by gangsters, and he seeks revenge. And spends a lot of time hunting down the killers, and finally finds them.
And now continues to seek vengeance and justice in Hell's Kitchen! While he has no actual superhuman powers, he is a master of
martial arts. His sensei, Stick, had taught him to master ninjutsu, aiki-jujutsu,
jujitsu, kung fu,
capoeira, judo,
aikido, wrestling,
stick fighting, and American-Style wrestling.

"I thought Daredevil was kind of cool because he couldn't do anything.
I mean, he's blind. It wasn't that he could fly. His major power was an impediment.
So I was intrigued. When I took over he was kind of like Spider-Man-lite,
but I was able to project a lot of my Catholic imagery onto it.
And I'd always wanted to do a crime comic."
-Frank Miller

"Violence doesn't discriminate. It hits all of us... the rich, the poor,
the healthy, the sick. It comes as cold and bracing as a winter breeze off
the Hudson. Until it sinks into your bones... leaving you with a chill you
can't shake. They say there's not rest for the wicked. But what about the
good? The battle of Good vs. Evil is never-ending... because evil always
survives... with the help of evil men. As for Daredevil, well... soon the
world will know the truth. That this is a city born of heroes, that one man
CAN make a difference."
